Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed August 12, 1912. Serial No. 714,567.

To all 'cv/0m it may concern Be it known that I, CHARLES B. DAVIS, acitizen of the United States, residing at New Yorkv city, in the countyof New York and State of New York, have invented certain new and usefulImprovements in Brewing Apparatus, &c., of which the following is aspecification.

My present invention relates to brewing apparatus, etc., and morespeciiically to apparatus for sieving or straining a liquid from solids.For example, in brewing, my improvements may be used with advantage inthe mash-tun for straining the extract from the spent grains or husks.

The features and advantages of my improvements will be apparent to thoseskilled in the art from an understanding of the following description inconnection with the drawings which show only two of the spe ciiicembodiments that my improvements are adapted to take.

Figure 1 is a vertical section of a mashtun having its bottom fittedwith my improved sieve means; and Fig. 2 is a similar view of amodification.

I will now describe the devices of the drawings, reserving it to theclaims to point out the novel features and to define the scope of theinvention, it being understood that the claims will be given the duerange of equivalents to which they may be entitled in view of the art.

Referring now primarily to Fig. 1, 1 is a niash-tun having a bottomportion 2 whose interior is provided with steps 3, 4t and 5, the lastbeing the actual inside-bottom of the tun. 6 is a perforated plate orsieve supported on the step 4c. Grate means is provided above the sieveconsisting of a plurality of tilting plates -7 hinging about axes 8, thefront edge of one plate being shown as overlapping the rear oi" thepreceding plate when they have been hinged down into closed position.The plates can be opened and closed like the slats of a shutter orVenetian blind. The parts are shown merely diagrammatically in thedrawings, but it will be seen that the means for operating the plates 7consists of gears. Thus, there is a gear 9 rigid with the hinge-axis ofeach plate 7, and there is a gear 10 operatively supported between eachpair of the gears 9 in mesh therewith. Qbviously, rotating one of thegears in any appropriate manner results in simultaneously raising orlowering all of the plates 7 depending upon the direction of rotation ofsaid gear. In the case of a mash-tun, the plates 7 are kept closed as-shown in Fig. 1 during the mashing operation. They thereby guard theperforations in the sieve 6 from becoming clogged. On the other hand,after the mashing operation, these plates 7 are hinged into verticalposition, which thereupon permits the extract to be strained ofi fromthe grains through the sieve 6 and out of the tun by way of the deliverypipe 12. Further, it is apparent that a variety of means for o-peratingthe guards might be adopted; furthermore, changes may be made in thesize or shape of the plates; also they may be mounted below instead ofabove the sieve. This is shown in Fig. 2 where 1 is again the mash-tunand 6 the sieve. The gate means consists of a plate or plates 14 hingedto the underside of the sieve. 15, 15 are screws tapped verticallythrough the bottom of the tun, said screws having their free endspivotally connected with the hinged plates 111 by the links 16 to hingesaid plates at will to and away from the underside of the sieve. In thisform of the device, the sieve perforations should be large because theyare unprotected from above against clogging but it has the advantagethat the opening of the gate does not disturb the mashing and said gatecan be opened more readily.

I repeat that I have illustrated the devices only diagrammatically andmodiications and changes might be made therein to accom plish thepurpose of the invention without depart-ing from its spirit.

What I claim is:

1. An apparatus for separating liquids from solids comprising a sieve;and a controlling gate comprising a plurality of hinged members, andmeans for operating them.

42. An apparatus for separating liquids from solids comprising a sieve;and a controlling gate comprising a plurality of hinged members andmeans for moving same into open and closed position.

3. An apparatus for separating liquids from solids comprising a sieve;and a con Vtrolling gate comprising a plurality of hinged members andmeans for hinging same into open and closed position, said gatemembersbeing located below the sieve.

4. An apparatus for separating liquids from solids comprising a sieve;and a controlling gate comprising a plurality of from solids, comprisinga sieve, and a pivoted gate adapted to be moved toward and from thesieve to open or close the apertures thereof.

In testimony whereof I aliix my signature 1 in presence of twowitnesses.
